The 59mm x 43mm Rippler is a micro, lightning-quick version of our Hot Spot shapes – ideal for smaller rides like mini cruisers, locker boards, filmers, and retro pool/park boards.  Frequently imitated by sellers of low-cost plastic boards, it was the first sub-60mm wheel on the market designed with classic race-oriented lip profiles.

This super agile and grippy shape is now combined with the world’s fastest ’thane so you can _roll, carve, and slash like never before!_  Poured in Seismic’s proprietary DEFCON – the urethane behind the World Speed Records for both Skateboard (91MPH) and Street Luge (101MPH). _Get ready for a whole new realm of FAST!_ 

Molded around our advanced Mini-EC hub.  Not too big and not too small, the Mini-EC hub preserves ample tire thickness while saving over ½-ounce per wheel, stiffening the inside edge, and super-charging inside edge rebound.
